Hey magicians!
I've been using the new whitewater system and have come across a glitch? How would I get rid of those small dots lining across the sim?
Also, would anyone know of a good place to learn just the whitewater system? It is a bit confusing when coming from the 16.5 WW system. The scene is supposed to be a stormy ocean for any feedback you may have, which I would love.
Thanks.

Hey Magicians! I recently started using Houdini, so my knowledge isn't as vast as some of you guys. I've been trying to figure out how to spawn whitewater along the top of a tsunami, however, I've been having lots of problems going in different directions. Through a lot of RND and research, I was able to get the flip fluid on the cusps but the whitewater just isn't spawning, I think I found the error, it has no "Point Groups: emitters 0". I've been able to copy spheres to the cusp and scatter pops to the cusp as well, but I need the whitewater (foam, spray) on the cusp instead and don't really know how to go about it. Other than for a project, I've been really interested in seeing how its done since so many people want to avoid it. Any help is much appreciated!

A few months ago I was watching “Avatar, the last air bender” for like 5ft time and wanted to create some bending control, I'm still working on the water bending, so here's a WIP from this weekedn.
Right now there's only to WIP, but will keep on with this until I master the 4 elements!

Hey guys working on a snow simulation setup for a student film for second year of my University course (University of Hertfordshire) -
Been working on some rnd' and so far happy with results but was wondering if anyone had any idea how to get rid of the crazy/flying like particles in my walking man RnD' -
Wasnt sure if more substeps/ constraint iterations / or if their was too much force from the colliding object to the snow - will provide a scene too!
- SNOW RND
- SNOW WALKTHROUGH TESTS
(For the shot in this the sim itself may just include dropping the snow ontop of a building for nice placement and not any actual interaction once stable so these tests maybe slightly uneccesary but would be nice to gage a further understanding!!) Will provide both houdini files if asked,
LEFT TEST;
1.4 million particles upressed to around 14million at render time
Constraint interations - 40
clumping stiffness - 40
Shock scaling power - 0.8
static threshold - 0.5
scale kenetic - 2
RIGHT TEST;
168,000 particles upressed to 4.2million (bit excessive in the upressing)
Constraint interations - 65
clumping stiffness - 40
Shock scaling power - 0.8
static threshold - 0.5
scale kenetic - 2
- thinking possibly my scale kenetic attribute is causing the excess velocity/movement on impact
(was testing more constraint interations vs higher particle seperation (more particles) which is more efficient )
- HIP File provided,
- Alembic geo file too - https://www.sendspace.com/file/8flg0v

A few days back I stumbled on a Minecraft renderer that took a long time to calculate, but could generate some nice pictures from Minecraft maps. I thought that I could cut down the rendertimes by importing them into Houdini and could also work on my Python skills in Houdini at the same time. There are some realy nice projects out there that could use a better render engine than provided in-game, or the slow one I found.
I've got the basics working, Houdini can now import the chunks, create the geometry and texture the blocks. The chunks are quite big (16x16x256 blocks) so I've build in some options to skip some chunks.
The main problem that I'm facing right now is speed. The pieces in the pictures below are already 3.3 milion poly's, so I need to find a way to cleverly cull the poly's you won't ever see. If you guys have some tips on this, please share them
Another problem is the texture filtering, is there an option to just keep the harsh edges in the textures that are in the game (Instead of filtering/blurring them).
Next up is entity support, and different geometry types that one can find in the game. Let me know what you guys think.

Dear odforce community,
we (WE CAN DANCE Animation Studio) are working hard on our Christmas Animation Short for 2012 - "Santa & Klaus". After several years of half baked attempts this is the first time we really committed to producing a true character animation piece. Everything is being done in Houdini except for the animation which we unfortunately had to do in Maya due to the limited amount of Houdini Rigging and Animation Artists. We are however interested in developing a full Houdini Character Animation pipeline in the future if we are sure to have enough skilled artists at our disposal (feel free to contact us).
With this animation piece we are venturing in several new areas that we haven't done before like skin shading and fur as well as the overall sheer amount of work that has to be done to finish something like this.
I would like to use this thread for three things. First to show you regular updates on our progress. Second to get some feedback (which however might not be implemented as our deadline is rather tight but is definitely appreciated and discussed). And third to get technical help if we might get stuck in an area we aren't very experienced in yet. I will try to post updates and pictures as regularly as possible.
Posts in this thread might be a little bit on the technical side while the artier (is this a word?) side can be seen at http://santa-und-klaus.tumblr.com
We hope you find this thread interesting and entertaining.
Best regards,
WE CAN DANCE Animation Studio
